  Objective: Many studies have confirmed the benefits of wearing Mouth-Guards (MG) on the prevention or reduction of sport-related stomatognathic system trauma. However, custom made MG with high adaptability can be retained in a dentition even when the mouth is open; this situation thought to increase jaw fragility and the possibility of trauma. This study investigated the effects of the clenching with MG, and occlusal support area difference on mandibular distortions related to injury caused by direct lateral impact. Materials and Method: A pendulum-type device was used to apply an impact on the lower-left region of the mandibular body of a skull model. MGs with different occlusal support areas were fabricated for various conditions. A pseudo-occlusal force of approximately 30 N was applied in the submental region for the model except for mouth..
